You didn't say what model Lexus you have or with how many miles, but
it could also be the idle speed control valve sticking.
************
Good point, although a sticking idle air control valve will often also
cause
poor idling even after the car is started.
I didn't list other possible causes in my original response because I
wanted
to know the mileage and maintenance history first, but here are some other
possible causes in addition to the sticking idle air control valve; dirty
or
clogged MAF sensor, dirty or clogged air filter, disconnected wiring,
problem with the coolant temperature sensor for the ECU and associated
wiring; worn spark plugs; problem with the ignition system, problem with
the
fuel delivery system, vacuum leak, leak in the intake snorkel between the
air filter and throttle body; restriction in the exhaust.
More information from the OP would make diagnosis a little easier.
